Based on people’s demand for indoor air quality monitoring, an ambient intelligence detection system with STM32F103C8T6 microcontroller as the core controller is designed, which can monitor current temperature, humidity, suspended particles (PM10) and toxic harmful gases in real time, accurately effectively. And environment transmitted to computer display through Bluetooth, so warn people time ...

This paper presents a comprehensive literature review of current progress in the application of state-of-the-art indoor positioning systems for telecare and telehealth monitoring. This review is the first in the literature that provides a comprehensive discussion on how existing wireless indoor positioning systems can benefit the development of home-based care systems. More specifically, this r...

The building plants represent one of the main sources of power consumption and of greenhouse gases emission in urban scenarios. The efficiency of energy management is also related to the indoor environmental conditions that reflect on the user comfort. The constant monitoring of comfort indicators enables the accurate management of building plants with the final objective of reducing energy was...

The reduced air quality inside buildings is undoubtedly a key factor to be controlled to ensure the health and comfort of the occupants as people usually spend more than 90% of their time in indoor environments. This paper aims to present iAQ an automatic system that is capable to monitoring indoor air quality and send real time notifications to provide active coaching for occupants in order to...

Japanese cedar pollinosis (JCP) is an important illness caused by the inhalation of airborne allergenic cedar pollens, which are dispersed in the early spring throughout the Japanese islands. However, associations between pollen exposures and the prevalence or severity of allergic symptoms are largely unknown, due to a lack of understanding regarding personal pollen exposures in relation to ind...

Introduction In this study, effective dose equivalent for the public due to internal exposure to 222radon (222Rn) was evaluated in three regions of Ramsar, a northern coastal city in Iran.                                Materials and Methods Measurements were carried out using a radon monitoring device. Outdoor and indoor radon concentrations were measured within 24 hours with an integration in...

RF MIMO Systems for Wide-Area Indoor Human Motion Monitoring by Chi Xu Department of Electrical and Computer Engineering Duke University Date: Approved: Jeffrey Krolik, Supervisor

Currently the research on the map visualization and GIS visualization is relatively mature. But in the indoor environment, Indoor positioning system requires monitoring the location which is on vector map of positioning data and display positioning data trajectory. At the same time, Indoor positioning environment is complex, and has many obstacles such as walls. The connection between two posit...
